Performance analysis of two-stage matrix converter driven asynchronous motor

The features of the two-stage matrix converter topology were analysed, and then the pulse-width modulation strategy for the rectifier side and the space vector pulse width modulation strategy for the inverter side were deduced. And the principle of zero current commutation was (elaborated.) The simulating model of the two-stage matrix converter was set up under MATLAB/SIMULINK. In order to investigate the starting-up and running process in AC frequency conversion for asynchronous motor, a lot of simulation researches were carried out. Simulation results demonstrate that the input current is sinusoidal input and in phase with the input voltage and the major component of output voltage is the fundamental component, which verify the correctness and availability of the proposed strategies and excellent performance of the two-stage matrix converter.
